Definitions

  • the invention relates to a condensation clothes dryer, in which the process air is circulated in a closed circuit and in the process air circulation, a heater for heating the process air, a cooling device for cooling moisture laden process air and a removable filter for binding and / or decomposing in the process air located odors is arranged.
  • DE 197 05 616 A1 discloses a tumble dryer in which a second, finer depth filter is connected downstream of a first lint filter, which can be cleaned under running water.
  • the depth filter is made of foam and therefore needs to be cleaned carefully. Furthermore, the effect of the depth filter is exhausted in an improved filter effect against the lint entrained in the air flow.
  • Another known tumble dryer (JP 11 300 096) with a filter arrangement has as a second filter a special filter sheet for deodorizing and antibacterial treatment of the effluent process air.
  • This filter sheet consists of specially coated nonwoven fibers.
  • This filter sheet is difficult to clean because it consists on the one hand of nonwoven fabric and on the other hand has a special coating (copper sulfide) on the fibers contained therein, which would be washed off during a treatment in a conventional washing process and the fibers would leach out of the nonwoven fabric dressing, so that a Impairment of the functional properties of the filter sheet would be the result. After a few cycles of use, therefore, such a filter sheet must be replaced.
  • the present invention has for its object to provide a condensation dryer of the type mentioned with an air filter extended functionality, which is also better to clean.
  • a condenser tumble drier described in the introduction, in which the filter for binding and / or decomposing the fragrances has a flexible fiber fabric or knitted fabric and is washable.
  • the said flexible fiber material provides a mechanical resistance of the filter, which allows a thorough cleaning in a washing machine. This material can thus be washed with a high mechanical energy input and also at high temperatures. In this way, the condition for a filter treatment is created, which makes it possible to sufficiently clean odor filter and / to regenerate.
  • the fiber material can be treated with particles of a substance that can bind odors and from which the odors can also be washed out again. These particles can be activated carbon or special minerals. It is also conceivable treatment of the fiber material with catalytically active substances that can decompose odors.
  • the fiber fabric or knitted fabric only has components that are so soft that damage to the washing machine can be avoided when washing the filter in a washing machine. As a result, it can be washed like normal laundry in a household washing machine without the risk of damaging the washing machine.
  • the fibrous web or fabric may be provided in a frame of the base and top of the filter for holding and stretching the fibrous web or web within the process air stream.
  • the fibrous web or knitted fabric may in this case consist of a section of a strand-finished filter material, so that it can be made available at very low cost.
  • the frame for the filter is advantageously removable from the tumble dryer to facilitate the insertion and removal of the filter.
  • the filter can be preceded by a coarse filter for removing particles from the air stream.
  • the filter can thus be protected against coarse particles, which could clog it or affect its effect.
  • the invention is used in a condensation clothes dryer, in which a control device is provided, which is set up such that the process air circulated in a closed circuit and in the process air cycle a heating device for heating the process air, a cooling device for cooling moisture-laden process air, the filter and an upstream lint filter are arranged as a coarse filter.
  • a frequent need of the user can be taken into account, which aims at ridding the laundry of unpleasant odors. This may be the case if the garment has been exposed to cigarette smoke and only ventilation of the garment is desired.
  • the odor filter is advantageously arranged within the process air circulation at the point where the best conditions for the removal of odors from the process air prevail. So z. For example, in the section between the cooler and the heater, the temperature of the process air is lowest and the relative humidity highest, and after the heater and before contact with the laundry to be dried, the temperature is highest and the relative humidity is lowest.
  • the control device of the condensation clothes dryer can advantageously be set up such that the process air can be heated and circulated to a temperature below the temperature usually used for tumble drying. So the laundry can be treated more gently and yet be ventilated, whereby the reduced temperature and energy can be saved.
  • the control device can be set up so that the process air can be circulated even when the cooling device is switched off. A cooling of the process air is not required when venting, since no moisture must be removed from the process air and thus further energy can be saved.
  • a blower 3 generates a drying air flow which is conducted to a heating device 4 and then through the perforated drum base into the drum 2.
  • the drying air flows through first the door 9, a coarse lint filter 6 and then the in Thereafter, the dry air is passed to a condenser 8 in which the drying air is cooled to condense the laundry moisture contained therein.
  • the condenser 8 is flowed through by cooling air which is sucked in by the environment of the household laundry drier 1. After flowing through the capacitor 8, the dry air is sucked in again by the blower 3.
  • the receptacle 7 shown in section in FIG. 2 serves as a holding frame for the odor filter 13.
  • the holding frame 7 has a flat shell-shaped lower part 11, the bottom of which has large openings for the passage of the process air.
  • a foldable top 12 can be folded down and locked, the upper part 12 can cover substantially the entire bottom of the lower part 11 and has openings that come to lie in the folded down state respectively over the openings in the lower part 11.
  • an odor filter 13 which for binding and / or decomposing the odors a flexible fiber fabric or Gewgewirk has (13) are held.
  • the odor filter 13 is treated with a substance that can bind odors and from which the odors can also be washed out again to regenerate the odor filter 13 and thus make it suitable for permanent use.
  • the odor filter 13 has no hard components and can thus be washed in a washing machine like ordinary laundry.
  • the receptacle 7 can be arranged from the outside, in particular by a special flap, in the process air cycle of the tumble dryer 1 and removed therefrom.
  • the tumble dryer 1 shown in Fig. 1 additionally has a control device 10 for driving the fan 3, the heater 4 and a further blower, not shown, which can supply the condenser 8 with cooling air.
  • the control device 10 is arranged such that in a program for releasing the laundry 5, the process air can be circulated at a reduced temperature when the drum 2 rotates, the fan for the condenser 8 being switched off in order not to unnecessarily cool the process air.
  • the normal drying program in addition to the temperature of the process air or the heating power of the heater 4 and the movement of the laundry drum 2 can be reduced.
